Description

本出願は米国特許法の第１１９条（ｅ）項に基づき、Ｋｅｎｒｉｃ Ｒｏｓｅによる２００３年９月２２日出願の米国仮出願第６０／５０４，１８８号の利益を請求する。   This application claims the benefit of US Provisional Application No. 60 / 504,188, filed Sep. 22, 2003, by Kenric Rose, based on Section 119 (e) of US Patent Law.

本発明は一般に、流体圧再生駆動システム（ｈｙｄｒａｕｌｉｃ ｒｅｇｅｎｅｒａｔｉｖｅ ｄｒｉｖｅ ｓｙｓｔｅｍ）用などの統合加圧流体システム（ｉｎｔｅｇｒａｔｅｄ ｐｒｅｓｓｕｒｉｚｅｄ ｆｌｕｉｄ ｓｙｓｔｅｍ）に関し、より詳細には、少なくとも１つの流体圧流体アキュムレータ（ｈｙｄｒａｕｌｉｃ ｆｌｕｉｄ ａｃｃｕｍｕｌａｔｏｒ）を収納する圧力容器アセンブリを含む統合加圧流体システムに関する。   The present invention generally relates to an integrated pressurized fluidized system, such as for a hydraulic regenerative drive system, and more particularly to at least one hydraulic fluid accumulator (fluidic fluid accumulator). It relates to an integrated pressurized fluid system including a pressure vessel assembly for housing.

従来の統合加圧流体システムでは、再生エネルギーはフライホイール・アキュムレータ、電気化学電池、または流体圧流体アキュムレータに通常蓄積される。後者は、既知の技術であり、他の再生および蓄積装置に比べて、注目すべきことに、それらを連結した自動車の変速機に関連した使用においてより柔軟性がある。他方において、それらは質量および体積に関して効率的でないままであり、したがって自動車への取り付けに重大な問題がある。得られたエネルギーの節約を不利にすることに加えて、死荷重および死容積（ｄｅａｄ ｗｅｉｇｈｔ ａｎｄ ｂｕｌｋ）のこれらの問題は、流体圧流体アキュムレータ自体または主にアキュムレータを取り付けるために自動車に加えられなければならない変更に関連する高いコストにつながる。結果として、流体圧流体アキュムレータを備えた自動車は、どのような方法でも、もはや標準ではなくなり、したがって、製造および維持するのにより多く費用がかかり、さらにこの設置に使用された装置を別の車両に移したり、大きさを調節したりできず、このことはそのような設置の全体コストを増加させる。   In conventional integrated pressurized fluid systems, regenerative energy is typically stored in flywheel accumulators, electrochemical cells, or hydraulic fluid accumulators. The latter is a known technique and, notably, is more flexible in use in connection with automobile transmissions connecting them compared to other regeneration and storage devices. On the other hand, they remain inefficient with respect to mass and volume, and therefore have significant problems in mounting on automobiles. In addition to penalizing the resulting energy savings, these problems of dead weight and dead volume must be added to the vehicle to install the hydraulic fluid accumulator itself or primarily the accumulator. Leading to high costs associated with changes that must be made. As a result, automobiles with hydraulic fluid accumulators are no longer standard in any way and are therefore more expensive to manufacture and maintain, and the equipment used for this installation can be transferred to another vehicle. Cannot be moved or resized, which increases the overall cost of such installation.

したがって、本発明の目的は、すべての蓄積機能を組み合わせ、いかなる実質的な変更もなく、流体圧流体アキュムレータを充填、放出するように設計された流体圧再生駆動システムを備える標準の自動車を含めて様々なタイプの加圧流体システムに取り付けることができるコンパクトな圧力容器アセンブリを提供することによって、従来技術のこれらの欠点を克服することである。   Accordingly, the object of the present invention includes a standard vehicle with a fluid pressure regenerative drive system that combines all the storage functions and is designed to fill and discharge a fluid pressure fluid accumulator without any substantial change. It is to overcome these deficiencies of the prior art by providing a compact pressure vessel assembly that can be attached to various types of pressurized fluid systems.

本発明は流体圧再生駆動システム用などの統合加圧流体システムで使用するための圧力容器アセンブリを提供する。   The present invention provides a pressure vessel assembly for use in an integrated pressurized fluid system, such as for a fluid pressure regeneration drive system.

And at least one cooling passage provided within the at least one inner tube and defined by a clearance between the at least one hydraulic fluid accumulator and the at least one inner tube. The pressure vessel assembly further includes a fluid storage compartment formed within the outer casing outside the at least one inner tube. The fluid storage compartment is at least partially filled with a working fluid such as oil.

本発明の加圧流体システムは、少なくとも１つの流体圧流体アキュムレータおよび圧力容器アセンブリの貯蔵区画内の作動流体の強制冷却用の冷却通路を通る強制空気流を可能にする冷却ファンを含む。   The pressurized fluid system of the present invention includes at least one hydraulic fluid accumulator and a cooling fan that allows forced air flow through a cooling passage for forced cooling of the working fluid in the storage compartment of the pressure vessel assembly.

本発明の加圧流体システムは、加圧ガス貯蔵庫（ｐｒｅｓｓｕｒｉｚｅｄ ｇａｓ ｒｅｓｅｒｖｏｉｒ）が外部ケーシング内の区画の内部の作動流体を加圧するために外部ケーシングの内部の区画と流体連通するように、外部ケーシングの外側の加圧ガス貯蔵庫をさらに含む。   The pressurized fluid system of the present invention is configured so that a pressurized gas reservoir is in fluid communication with an internal compartment of the outer casing to pressurize working fluid within the compartment within the outer casing. It further includes an outer pressurized gas reservoir.

さらに、本発明の好ましい実施形態によれば、流体圧流体アキュムレータが、少なくとも１つのスパイラル・ラッピング（ｓｐｉｒａｌ ｗｒａｐｐｉｎｇ）が流体圧流体アキュムレータの周りを囲んだ状態で、内部管の内部に間隔を置き中心に合わせて内部管の内部に置かれる。   Further in accordance with a preferred embodiment of the present invention, the hydraulic fluid accumulator is spaced and centered within the inner tube with at least one spiral wrapping surrounding the hydraulic fluid accumulator. To be placed inside the inner tube.

さらに、本発明の好ましい実施形態によれば、圧力容器の外部ケーシングは、ほぼ管状のハウジングと、ハウジングの反対側の末端（ｏｐｐｏｓｉｔｅ ｄｉｓｔａｌ ｅｎｄｓ）に固定された端部材とを含む。   Further in accordance with a preferred embodiment of the present invention, the outer casing of the pressure vessel includes a generally tubular housing and an end member secured to the opposite end of the housing.

It is. Alternatively, the motor / pump 2 is a variable displacement fluidic unit. It will be understood that any suitable hydraulic motor / pump unit is within the scope of the present invention. In an application of an automotive fluid pressure regeneration drive system (not shown), the motor / pump 2 is connected via a drive shaft 3 to an automotive drive line.

図１にさらに示されるように、圧力容器アセンブリ１０は、少なくとも１つ、好ましくは複数の流体圧流体アキュムレータ２０を収納し、大気圧または低圧で、少なくとも部分的に油などの作動流体圧流体１７で作動流体貯蔵区画１１をその中に画定する。任意の適切なタイプの流体圧流体アキュムレータを使用できることが理解されるであろう。好ましくは、流体圧流体アキュムレータ２０は、当技術分野で知られている流体圧−空気圧式アキュムレータである。各流体圧−空気圧式アキュムレータ２０は、モータ／ポンプ２に連結された連絡ポート（ｃｏｍｍｕｎｉｃａｔｉｏｎ ｐｏｒｔ）２１と、ガス充填ポート２３とを含む。   As further shown in FIG. 1, the pressure vessel assembly 10 houses at least one, preferably a plurality of hydraulic fluid accumulators 20, and is at least partially at working pressure 17, such as oil, at atmospheric or low pressure. A working fluid storage compartment 11 is defined therein. It will be appreciated that any suitable type of hydraulic fluid accumulator can be used. Preferably, the fluid pressure fluid accumulator 20 is a fluid pressure-pneumatic accumulator as is known in the art. Each hydraulic-pneumatic accumulator 20 includes a communication port 21 connected to the motor / pump 2 and a gas filling port 23.

さらに好ましくは、圧力容器アセンブリ１０の貯蔵区画１１内の流体圧流体１７は、図１に示されるように貯蔵区画１１と流体連通された外部加圧ガス貯蔵庫６によってもたらされる低圧である。好ましくは、外部加圧ガス貯蔵庫６は、低圧ガス・アキュムレータまたは加圧下の適切なガスを収納するガス容器の形状である。したがって、圧力容器アセンブリ１０の貯蔵区画１１は、モータ／ポンプ２に連結された低圧アキュムレータを作る。さらに好ましくは、圧力容器アセンブリ１０は、モータ／ポンプ２に流体連通された３つの流体圧流体アキュムレータ２０を収納する。図１にさらに示されるように、モータ／ポンプ２は、分配ブロック７を介して流体圧流体アキュムレータ２０と圧力容器アセンブリ１０の貯蔵区画１１の両方に流体連通される（ｆｌｕｉｄｌｙ ｃｏｎｎｅｃｔｅｄ）。   More preferably, the hydraulic fluid 17 in the storage compartment 11 of the pressure vessel assembly 10 is at a low pressure provided by an external pressurized gas reservoir 6 that is in fluid communication with the storage compartment 11 as shown in FIG. Preferably, the external pressurized gas reservoir 6 is in the form of a low pressure gas accumulator or a gas container that houses a suitable gas under pressure. Thus, the storage compartment 11 of the pressure vessel assembly 10 creates a low pressure accumulator coupled to the motor / pump 2. More preferably, the pressure vessel assembly 10 houses three hydraulic fluid accumulators 20 that are in fluid communication with the motor / pump 2. As further shown in FIG. 1, the motor / pump 2 is fluidly connected to both the hydraulic fluid accumulator 20 and the storage compartment 11 of the pressure vessel assembly 10 via the distribution block 7.

Each of the plurality of cylindrical inner tubes 18 has a longitudinal axis 19 that is substantially parallel to the central axis 13 of the cylindrical housing 14, and includes one hydraulic accumulator 20 that fits inside the inner tube 18 with a nominal clearance. Sized to receive. The clearance between the hydraulic fluid accumulator 20 and the inner tube 18 receives a flow of a suitable cooling fluid, such as air, through which the internal operation of the hydraulic fluid accumulator 20 and the storage compartment 11 of the pressure vessel assembly 10 is performed. A cooling passage for cooling the hydraulic fluid is defined. Preferably, the nominal clearance is approximately a quarter inch.

さらに好ましくは、内部管１８はハウジング１２とほぼ同じ長さであり、平らな端部材１５および１６を通って延びる。すべての内部管１８は、それらの端部が同一面になるように組み立てられる。これを実現するために、対応する丸い穴２２が内部管１８が適合するように圧力容器アセンブリ１０の各端部材１５および１６に開けられる。したがって、作動流体貯蔵区画１１が円筒ハウジング１４の内部周辺表面１４ａと内部管１８の外部周辺表面１８ａと端部材１５および１６との間の空間によって画定される。   More preferably, the inner tube 18 is approximately the same length as the housing 12 and extends through the flat end members 15 and 16. All inner tubes 18 are assembled so that their ends are flush. To accomplish this, a corresponding round hole 22 is drilled in each end member 15 and 16 of the pressure vessel assembly 10 so that the inner tube 18 fits. Thus, the working fluid storage compartment 11 is defined by the space between the inner peripheral surface 14 a of the cylindrical housing 14, the outer peripheral surface 18 a of the inner tube 18 and the end members 15 and 16.

流体圧流体アキュムレータ２０が、当分野の技術者に知られている任意の適切な手段によって圧力容器アセンブリ１０の内部管１８の内部に固定される。例として、圧力容器アセンブリ１０の内部の流体圧流体アキュムレータ２０を強固に固定するように、内部管１８の遠位端を、内部管１８の反対側の末端にねじ付きファスナまたは溶接などで取り付けられた穴あき円形カバー部材２５（図６および７に図示）で閉じることができる。図示されたように、各カバー部材２５は冷却流が内部管１８の内部の冷却通路を通ることを可能にする複数の冷却穴２７を備えている。   A hydraulic fluid accumulator 20 is secured within the inner tube 18 of the pressure vessel assembly 10 by any suitable means known to those skilled in the art. As an example, the distal end of the inner tube 18 may be attached to the opposite end of the inner tube 18, such as with a threaded fastener or weld, so as to firmly secure the hydraulic fluid accumulator 20 within the pressure vessel assembly 10. It can be closed with a perforated circular cover member 25 (shown in FIGS. 6 and 7). As shown, each cover member 25 includes a plurality of cooling holes 27 that allow the cooling flow to pass through a cooling passage inside the inner tube 18.

組み立てられた状態で、端部材１５および１６は、円筒ハウジング１４の中に挿入され、かつ互いに平行にまたハウジング１４の中心軸１３に垂直に位置合わせされる。十分な溶接材料を、端部板１５および１６それぞれの隆起したフランジ１５ａおよび１６ａと円筒ハウジング１４の内部周辺表面１４ａの間に付けることができるように、端部材１５および１６は十分に引っ込めて作られる。端部板１５および１６を位置合わせするとき、内部管１８を完全な円筒ハウジング１４ならびに端部材１５、１６を貫通して通しハウジング１４と同一面で位置合わせできるように、両方の端部材１５および１６の穿孔された円形の穴２２を位置合わせしなければならない。内部管１８が配置されると、圧力容器アセンブリ１０の所望の圧力定格に合わせて漏れ止めされるように、十分な溶接が端部板１５および１６の隆起したフランジ１５ａおよび１６ａならびに円筒ハウジング１４の遠位端に加えられる。圧力容器アセンブリ１０は、材料厚および溶接が、適切な安全係数を備えてシステムの作動圧力を収納するのに十分なように設計されるべきである。   In the assembled state, the end members 15 and 16 are inserted into the cylindrical housing 14 and aligned parallel to each other and perpendicular to the central axis 13 of the housing 14. The end members 15 and 16 are made sufficiently retracted so that sufficient welding material can be applied between the raised flanges 15a and 16a of the end plates 15 and 16 and the inner peripheral surface 14a of the cylindrical housing 14, respectively. It is done. When aligning the end plates 15 and 16, both end members 15 and 16 are aligned so that the inner tube 18 can pass through the complete cylindrical housing 14 and the end members 15, 16 and flush with the housing 14. Sixteen perforated circular holes 22 must be aligned. Once the inner tube 18 is in place, sufficient welding will result in the raised flanges 15a and 16a of the end plates 15 and 16 and the cylindrical housing 14 being leak-tight to meet the desired pressure rating of the pressure vessel assembly 10. Applied to the distal end. The pressure vessel assembly 10 should be designed such that the material thickness and welds are sufficient to accommodate the operating pressure of the system with an appropriate safety factor.

本発明の好ましい実施形態による加圧流体システム１の圧力容器アセンブリ１０は、圧力容器アセンブリ１０を通る強制空気流によって、圧力容器アセンブリ１０のハウジング１２の効率的な冷却をさらに可能にする。この目的のために、図１に示されるように、加圧流体システム１は、内部管１８の外部周辺表面１８ａを通る圧力容器アセンブリ１０の流体圧流体アキュムレータ２０、内部管１８および貯蔵区画１５の強制冷却のための流体圧流体アキュムレータ２０と内部管１８との間のクリアランスによって画定される冷却通路を通る空気流Ｆを可能にする冷却ファン４を含む。好ましくは、電子制御器（図示せず）によって選択的に動作される電気モータ５によって冷却ファン４は選択的に駆動される。したがって、冷却ファン４の空気流Ｆは、流体圧アキュムレータ２０の外部周辺表面からの強制熱伝達をもたらす。   The pressure vessel assembly 10 of the pressurized fluid system 1 according to a preferred embodiment of the present invention further allows efficient cooling of the housing 12 of the pressure vessel assembly 10 by forced air flow through the pressure vessel assembly 10. For this purpose, as shown in FIG. 1, the pressurized fluid system 1 includes a hydraulic fluid accumulator 20, an inner tube 18 and a storage compartment 15 of the pressure vessel assembly 10 that passes through the outer peripheral surface 18 a of the inner tube 18. It includes a cooling fan 4 that allows an air flow F through the cooling passage defined by the clearance between the hydraulic accumulator 20 and the inner tube 18 for forced cooling. Preferably, the cooling fan 4 is selectively driven by an electric motor 5 that is selectively operated by an electronic controller (not shown). Accordingly, the air flow F of the cooling fan 4 provides forced heat transfer from the outer peripheral surface of the fluid pressure accumulator 20.

さらに、本発明の好ましい実施形態によれば、図２に示されるように、流体圧流体アキュムレータ２０が、少なくとも１つ、好ましくは２つのスパイラル・ラッピング２６が流体圧流体アキュムレータ２０の周りを囲んだ状態で、内部管１８の内部に中心に合わせて間隔を置き内部管１８の内部に置かれる。これらのスパイラル・ラッピング２６の性質が、流体圧流体アキュムレータ２０を内部管１８の内部に固定し、内部管１８の内部周辺表面と流体圧流体アキュムレータ２０の外部周辺表面の間の強制空気循環も可能にすることになる。したがって、強制空気流Ｆの乱流に寄与すること、ならびに強制空気流Ｆの経路を長くし、したがって強制空気流Ｆおよび内部管１８およびアキュムレータ１８が接触する時間を長くし、したがって熱伝達を増加させるのに役立つことの両方によって、スパイラル・ラッピング２６は流体圧流体アキュムレータ２０および圧力容器アセンブリ１０の冷却貯蔵区画１１内部の作動流体圧流体１７の冷却効率を増加させる。好ましくは、スパイラル・ラッピング２６は内部管１８の内部の流体圧アキュムレータ２０の減衰振動用のエラストマー材料製である。   Furthermore, in accordance with a preferred embodiment of the present invention, as shown in FIG. 2, the hydraulic fluid accumulator 20 has at least one, preferably two spiral wrappings 26 surrounding the hydraulic fluid accumulator 20. In the state, the inner tube 18 is placed inside the inner tube 18 at a distance from the center. Due to the nature of these spiral wrappings 26, the fluid pressure fluid accumulator 20 is fixed inside the inner tube 18, and forced air circulation between the inner peripheral surface of the inner tube 18 and the outer peripheral surface of the fluid pressure fluid accumulator 20 is also possible. Will be. Therefore, it contributes to the turbulent flow of the forced air flow F, and lengthens the path of the forced air flow F, thus increasing the time for which the forced air flow F and the inner pipe 18 and the accumulator 18 are in contact, thus increasing the heat transfer. By both helping to do so, the spiral wrapping 26 increases the cooling efficiency of the hydraulic fluid accumulator 20 and the working hydraulic fluid 17 within the cooling storage compartment 11 of the pressure vessel assembly 10. Preferably, the spiral wrapping 26 is made of an elastomeric material for damped vibration of the fluid pressure accumulator 20 inside the inner tube 18.

さらに、圧力容器アセンブリ１０の貯蔵区画１１の内部の作動流体圧流体１７から内部管１８への熱伝導速度を増加させ、貯蔵区画１１の内部の流体圧流体運動量を低減させ、かつ圧力容器アセンブリ１０を強化するために、外部ケーシング１２の内部で多数の内部バッフル２８が使用される。内部バッフル２８の配置を、自動車の様々な傾斜角に適合するように変えることができることが当分野の技術者によって理解されるであろう。   Further, the rate of heat transfer from the working fluid pressure fluid 17 inside the storage compartment 11 of the pressure vessel assembly 10 to the inner tube 18 is increased, the fluid pressure fluid momentum inside the storage compartment 11 is reduced, and the pressure vessel assembly 10 A number of internal baffles 28 are used inside the outer casing 12 in order to strengthen. It will be appreciated by those skilled in the art that the arrangement of the internal baffle 28 can be varied to accommodate various vehicle tilt angles.

アキュムレータ２０を流体で充填することを可能にするために、十分な作動流体圧流体１７をハウジング１４の内部周辺表面１４ａと内部管１８の外部周辺表面１８ａと端部材１５および１６との間の圧力容器アセンブリ１０の貯蔵区画１１の内部に収納できるように加圧流体システム１全体が大きさを調整される。   In order to allow the accumulator 20 to be filled with fluid, sufficient working fluid pressure fluid 17 is applied to the pressure between the inner peripheral surface 14a of the housing 14, the outer peripheral surface 18a of the inner tube 18, and the end members 15 and 16. The entire pressurized fluid system 1 is sized so that it can be contained within the storage compartment 11 of the container assembly 10.

圧力容器アセンブリ１０の圧力容量ならびに熱伝達容量の両方を最適化するために、圧力容器要素の材料および厚さの選択に配慮がされるべきである。   In order to optimize both the pressure capacity and the heat transfer capacity of the pressure vessel assembly 10, consideration should be given to the choice of material and thickness of the pressure vessel element.

圧力容器アセンブリ１０の円筒の設計も、システム重量の関数として圧力容量を最適化する。円周の周りを囲む、それぞれ隆起したリップ１５ａおよび１６ａを備える平らな端部材１５および１６は、円筒ハウジング１２への外部連結、ならびに内部管１８への連結を強くする。   The cylinder design of the pressure vessel assembly 10 also optimizes the pressure capacity as a function of system weight. Flat end members 15 and 16 with raised lips 15a and 16a, respectively, surrounding the circumference provide a strong external connection to the cylindrical housing 12 and to the internal tube 18.

設計も流体圧流体アキュムレータ２０の保護の増加を可能にする。この保護は円筒ハウジング１４と作動流体圧流体１７と内部管１８ならびに分離距離とから構成される。設計は弾道の貫通から充填されたアキュムレータ２０の保護を増すことが意図される。この保護に加えて、設計は穴を開けられたアキュムレータから放出された任意の流体の方向を変えることも可能にする。設計の性質が圧力容器アセンブリ１０の端部からの任意の作動流体の流れを導く。完全なシステムの賢明な配置／方向付けが、任意の放出された流体の流れを安全な方向に導くことになる。   The design also allows for increased protection of the hydraulic fluid accumulator 20. This protection consists of a cylindrical housing 14, a working fluid pressure fluid 17, an inner tube 18 and a separation distance. The design is intended to increase the protection of the filled accumulator 20 from ballistic penetration. In addition to this protection, the design also allows the direction of any fluid discharged from the perforated accumulator. The nature of the design guides any working fluid flow from the end of the pressure vessel assembly 10. The judicious arrangement / orientation of the complete system will guide any discharged fluid flow in a safe direction.
